Be it known that I, GEORGE W. Swn'r, Jr., a citizen of the UnitedStates, residing at. Bordentown, in the county of Burlington and Stateof New Jersey, have invented certain new and useful Improvements in FeedMechanism for Slotting and- Creasing Machines, of which the following isaspecificatlon. I

The object of this invention is to provide a machine which will mostefficiently slot and crease material, su h as card board or. corrugatedcard, for the formation of boxes, cartons, or containers, therefrom,thesame' being a division of application Serial No. 200,698filedNov-erfiber 7, 1917. 4

isasection on line 27-27 of-Fig. 1; Fig.

of the invention comprises a v forward portion thereof extends ahorizontal feed table comprising spaced channel irons ;5, between theupper while the said table by means of bolts 8.: Abovethe forw-ardmostportion of the said'table piled, from which position they are designedto be fed into the machine as will now-be described.

Suitably journaled in the channel iron side bars 5 adjacent to the frontand rear ends of feed table 6 are the transverse shafts 79' and 86-carrying respectively the. spaced sprocket .WhQBlS 80, .80 and 87, 87upon which are the-laterally inclined slots formed in the table 6 toreceive the chains. An adjustable angle-iron side gage 6 is mounted uponthe feed table 6 at the side towardwhichthe sprocket chains 8.8 incline,so that the feed bars 89, moving in their inclined path, continuallyurge thesuccessive blanks into gaging contact with gage 6 and insure thefeed of the blanks to the machine in proper position; The tension of thesprocket chains 88 ,may' be maintained as desired by meansof idlers 90,carried upon the free 'ends of de pending pivotally mounted members 91.

The blank-feeding mechanism just de-' scribed is suitably geared to theslotting and creasing machine to permit the convenient adjustment andtiming of the feed to correspond with the work' to be performed. I

' prefer to accomplish this result by the ed at 85 upon the frame 3 bywhich the gearcarried mechanism shown particularly in Figs.- 1, 3, 27and 28 of the drawings inwhich a gear wheel 78 is adjustably mountedupon the shaft 79 by means of a disk 7 8' whichis fast uponthe shaft andisdeta'chably secured to gear 78 by means of-screw. bolts 82. Pins 83project" laterally from gear 78 (at diametrically opposite points) inposition to be engagedby a latch member 84 p ivotally mountis' heldagainst movement whenfreedfrom the shaft 79. Gear 78 meshes with and isdriven by .an idler pinion 77, which "is in turn driven by a pinion 20on shaft 16 hereinafter referred to. The shaft 79 also has a hand-wheel81 secured to it, by which the feed mechanism can be manually adjustedwhen the gear 78 is freed on sh'aft 79.

In adjusting the feed mechanism for a given size of box blank themachine is stopped with the first pair' of creasing members"(presentlyto be described) in a given osition, such for instance as that shown inig. 2, and the latch member 84, is moved into engagement. with one ofthe pins 83, by thegear 7.8. Said gear. is then freed from its shaft 79by unscrewing bolts 82,'as described and shaft 79 is revolved by meansof the hand-wheel 81, until a feed bar 89, abuts against the rearmostedge of the desired blank resting upon the table 6 and having itsforward-edge in the desired relationship with said first set of creasingmembers. The screw-bolts 82 are then tightened member 84 is disengagedfrom pin 83, after which each successive blank will be fed into themachine in'exactly the desired position. This feeding mechanism iscovered by my divisional application Serial No. 27v ,550, filed February17th, 1919.

Successive blanks are taken from the shelf 9 and placedupon feed table 6over which they are carried by the feeding mechanism above described andpresented to feed rolls 15 carried by transverse shafts 16, 16' (seeFig. 7). Said shafts are journaled in side frames 3 and 4, the uppershaft 16 carrying a pinion 17, at one end meshing with an idler pinion18, substantially above it and rotatably carried by apin 19 secured tothe frame 4,' while the lower of said shafts 16 has securedtheretothe'pinion 20, meshing in turn with an idler pinion 21, revolvablycarried' by a pin 22, secured to the frame 3.

As each blank approaches the feed rolls. 15 its forward edge is raisedby the spaced arms. 95 mounted upon the rock shaft 96 and movableupwardly through spaced slots 97 in the feed table 6. The outer end ofthe shaft 96 carries a slotted crank-arm 98 to which is adjustably'journaled one end of a rod or pitman 99 having its other end Y jjournaled upon an operating crank mounted upon a'suitably timed shaftofthe machine.

to lock the gear 78 upon its shaft, and latch I prefer to construct thisoperating crank" in the form shown in Figs. 1, 25 and 26,-in which asegmental crank-arm 101, having a crank-pin-opening 100, is securelyvbolted to one edge of the outer face of a removable and adjustable ringor collar 102,which is radially enlarged uponthe side 0 positearm 101and suitably slotted, as at 1 3,104, to form an integral spring tongue105, which constitutes part ofthe wall of the circular bore or openingof the ring or collar that fits the outer end of one of the machineshafts such as shaft 25. The enlarged portion of the. ring or'collar102, is formed with 'a threaded radial opening 102 adjacent to the freeend .of the spring tongue 105 to" receive a screw. bolt 106, which isadapted to engage tongue 105 and firmly clamp it against the surface ofthe shaft 25 for securing the ring or collar in the desired adjustedposition thereon. The segmental arm 101 is so proportioned withreferenceto the diameter of the ringor collar 102 that the crank-pinopening 100will be eccentric to the shaft 25 with the result that the rotation ofshaft 25' will intermittently raise and lower the arms 95 for thepurpose explained.

The blanks pass from feed rolls 15 to'the creasing members mounted uponthe vertically spaced shafts 25, 25' journaled in bearings 26 carried byside frames 3 and 4. These shafts 25, 25 are provided with two and madeup of gears 27, 27'

sets of intermeshing gears, one set secured to the shafts outside oftheframes 3 and 4 on shaft and gears 28, 28 on shaft 25, while the otherset is secured to the shafts inside of the side frames 3 and 4andcomprises gears 37,37 upon the shaft 25 and the gears 38, 38 upon theshaft 25, The 'intermeshing gears outside of the side-frames arenormally fixed upon their shafts, although it is preferred toprovidemeans. by which they can be relatively adjusted. The intermeshinggears insidegof the-"side frames are adjustably mounted upon therespective shafts for the purpose which-will presently appear.

The shafts'25, 25' are also provided with series of spaced wheels orcollars indicated at 29 and 33 for supporting two pairs of relativelyadjustable male and female creasing members, which are preferably in theform of suitably shaped rigid bars.' One pair of said creasing 31 and32, is carried by suitable brackets secured'to and supported by thewheels or pulleys 29 and 33. The creasing members of the other pair, aresecured at their opposite ends to suitable flanges or pulleys 36, whichare rigidly attached to the inner intermeshing gears 37 37' and 38, 38.which are so mounted upon the shafts 25, 25" that they may be freedprloosened thereon to permit their supporting shafts to independentlyrotate in said gears when the gears and their attached creasing .membersare held against motion. Upon the bar 201 extending across the machineand supported in brackets upon the side frames 3 and 4 are mountedadjustable-gear looking members 200, one of which is shown in detail inFigs. 14, 15 of the drawings. Each of these locking members isadjustably keyed upon its supporting bar and provided with two inwardlypresented gear-engaging teeth 202. These locking members 200 can bemoved longitudinally upon their supporting bar so as to intermesh withthe teeth of gears 37 37 to hold said gears and the gears 38, 38 againstincrement when the gears and connected creasing members are loosenedupon their shafts. With the intermeshing gears so shafts carrying thefixed pair of creasing 3 11"- are rotated in the desired direction tochange the circumferential distance between the fixed and adjustablepairs of'creasing members ti suit the desired size of box blanks thatare to be made. When the desired ad ustment has been effected, the innerset of intermeshing gears 37, 37 and 38, 38', with their =ttacliedcreasing members are again securely fastened te their respective shaftsand the locking-members 200 moved out of engagement with the gears 3737,

when said properly adjusted pairs of creasing members will be ready tocofiiperate in members, indicated at indicated at 34 and I the saidframes constantly locked against motion, the.

the production. of box blanks of the desired size. Suitable provision ismade for fastening locking members 200 upon bar 201 in eitherof theirengaged or disengaged posi-. tions.

Continuing onward the board, which is in the process of passes betweentwo vertically spaced horizontally positioned shafts 40 and 4O journaledatv their opposite ends through bearings 41, carried by the respectiveframes 3 and 4 of the machine, said shafts each carrying'at theiradjacent ends interlocking gears 42, which latter mesh in turn. withgears 43 and 44 rotatably journaled on pins 44' on side frame 3 andrespectively above and-below said first-mentioned gears. These shaftshave secured thereto pairs of longitudinally adjustable rotary trimmingknives 45 and 46 for cutting to the desired length the board as itpasses therebetween, said shafts also -bein provided with spaced pairsof feed rolls 4 for insuring a continued and uninterrupted passage ofthe 'said blanks.

Still further as the blank continues through the machine, it passesbetween a pair of vertically spaced, parallel, horizontally extendingshafts 50 and 50 through bearings51 in the respective frames 3 and 4 ofthe machine and carrying upon their outermost end portions and outsideof interlocking gears 52-52 and 53-53 respectively, while between thesaid frames the said shafts carry spaced pairs of collars 54, securedthereto and in turn carrying flat bars 55, provided upon their latterlyopposite sides with radially inwardly converging surfaces to provide adove-tail'cross-section (as shown in Figs. 8 and 10). Further.surrounding the said shafts 50 and 50 are spaced pairs of collars 56, towhich are secured flat bars 57, of dove-tail cross-section like the bars55 above described, the opposite end portions of said bars 57 beingsecured indirectly to constantly interlocking pinions 58-58 and 59-59,respectively, mounted upon shafts 50, 50 inside the side frames 3 and 4.These gears 59, 59 upon shaft 50' are geared respectively to the gears38, 38' upon shaft 25 termediate pinions 220 journaled upon studshaftson inner sides of frames 3 and 4. By this gearing the inner setsof gears 37, 37', 38, and 53, 58', 59, 59" will always act in unison andbe held against motion when locked by member 200.

The two bars 55 carry inter-engaging dies 60 and 61 as hereinafterdescribed, while the. said bars 57 also carry spaced pairs ofcoiiperating dies 62 and 63, which latter can be shiftedcircumferentially about their respective shafts by temporarily looseningthe formation into a box blank,-

by means of injournaled respective collars to said shafts. in fixedposition, thus by saidadjustment adapting the machine to form blanks forvarious sizes of boxes. For the purpose of forming blanks such as thatshown in Figs 39, a set of dies 64 and 65 (Fig. 4) are secured to thebars 57 at the end-portions adjacent to the frame 3 and of aconstruction hereinafter described. From between the last-named pair ofshafts the blank passes onward between a pair of rolls 67, which operateto remove said blank from the (lies between which it has just passed,and to deliver it to a platform or the like as may be desired.

For driving the various elements of this machine there is provided acounter shaft 70, preferably carrying a belt pulley 71 and a pinion 72,said shaft being journaled through spaced bearings orbrackets 73, de

pending from the underside of the bed plate 1. The pinion 72 meshes witha gear 74, secured to the shaft 50 which by means of the interlockinggears 52.-52' and 53-53 rotates shaft 5O. The gear 52 meshes with thepinion 43 which by means of the cooperating pinion 42 also drives pinion44 which latter meshes directly with the gear 28, cooperating with gear27. Also meshing with gear 28, is the pinion 21 which turn the pinion 20of the shaft 16 while meshing with the gear 27' is the pinion 18 whichalso cooperates with the pinion 17, of the shaft 16. The rolls 67 aredriven by idler pinions 67 intermeshing with ears 52 and 53.

Re erring to Figs. 20 and 21, an auto- .matically adjustable feed rollsegment is shown in detail, the position of the same within the machinebeing shown clearly in Fig. 2 immediately adjacent to the upper andlowermost creasing members carried by the shafts 25 and 25. This'rollsegment esber in operation to provide for the useof various thicknessesof paper, cardboard, corrugated board, or the like, in the manufactureof. box blanks.

In Figs. 22, 23 and 24 is shown in detail another form of segmental feedroll comprising abody portion 118 provided with a radially extendingflange 119 from whichprojects laterally an integral shoulder 120 in turnprovided with a radially outer face 121 formed upon an are about thecenter of theshaft upon which said roll is mounted,

-member of a set of cooperating segmental pairs thereof for insuring apositive feed of the box material through the machine and it is to benoted that while one of the members of each pair is mounted upon each ofthe shafts 25, 50 and constructed as shown, the other is mounted uponeach of the shafts 25, 50 and is substantially the same except for thefact that its feed surface is an integral part of its body and is notadapted to yield from its normal position as material of variousthicknesses comes into contact therewith. The members shown comprise asemi-circular yoke portion 125, having apertured reduced end portions126 fitting between'and pinned to the lugs 127 of the bifurcated ends ofa second semi-circular yoke member 128. Extending radially from thecentral portion of the member 125 and integral therewith is an arm 129provided with an enlarged head portion 130, adjacent to which ispositioned in parallel relation therewith a segmental feed plate 131.Said plate is provided with inwardly extending pins 132 adapted topass'slidably through relatively larger radially extending apertures 133in the head 130, said pins being prevented from more than predeterminedmovement by pins 134 extending transversely through the inner endportions thereof. The head portion 130 is also provided with enlargedrecesses 135 extending.,inwardly from its outer surface and adapted toform cups for the retention of coil-springs 136, which at their outerfree ends press against the inner surface of the feed plate 131 and tendto maintain the same yielding in its outermost position. Thesesegmental-feed members are used only when working upon sheets which aretoo narrow to reach from the shafts 16, 16 to I the shafts 40, 40.

The rotary punches and dies carried by the shafts 50 and 50 are shown indetail in Figs. 8 to 11, inclusive. As hereinbefore described, saidshafts are encircled by collars 56 having secured thereto longitudinallyextending dove-tailed bars 57, while adjustably' mounted upon the latterare the supporting members for the punches and dies on the shaft 50,each of the punch supporting members 140 has a beveled sur-' face 141adapted to cooperate with one edge portion of said bar and is providedalso with an adjustable member 142 having a beveled surface 143 adaptedto adjustably grip the, edge portion of said bar. The

outermost surface of the member 140 is pro- 158 formed with of similarlyextending apertures 155, in portion 151. Die

inclusive.

vide d with a radially inwardly extending longitudinal recess 144, inwhich is adjustably positioned a ground segmental punch member 145 bymeans of set screws 146.

Positioned upon the shaft 50 and exactly in alinement with the punch andmounting 'ust described, is a corresponding die and its mounting.Specifically, this. latter comprises a segmental die supporting membersuitable integral strengthening ribs on one lateral face and acurvedshouldered recess in its other lateral face to receive acircumferentially adjustable member 150 having a transversely extendingportion 151 recessed upon its outer surface'152 and adapted to receive aground die plate 153, having a longitudinally extending aperture 154,the sides of which taper radially outwardly and lie substantially inplanes with the corresponding sets plate 153 is secured in recessed face152 by suitable means, not illustrated. Plate 153 is omitted from Fig.8. The box blank shown in Fig. 39 illustrates the shape of slits cut bypunches 145 and dies 153, while the shape of a box blank formed by thesole use of such dies as that shown in Fig.37 is shown in detail in Fig.

40. Each of the members 150 is adjustably secured bymeans of a bolt156', passing slidably through elongated apertures 157 to a member 158,which in turn is provided with.

a diagonally disposed surface 159, adapted to cooperate with one side ofthe dovetailed bar 57 carried by the collar 56, while the oppositesideof said bar is held by a member 160, secured by a bolt to the memher158.

For forming the cut-out portions 170 shown at one end ofFig. 39 andadapted thereby to create a tapered tongue 171, flap dies and punchesare provided such as are shown in plan detail in Figs. 16 to 19, Thepunch two cut-out portions as the box material passes through themachine, while the punch and die pair of Fig. 19 forms the second ofsaid portions. in construction and operation and the punch of eachcomprises a shearing bar 175, having a cutting edge 176, while said baris curved outwardly at 177 and provided with the flap cutting edge 179,said bar also beremovably secured within angularly related slots 178within the radially outer surface of a base member 180 secured by bolts181 to a member 182 in turn removably and 'adjustably secured to thedove-tailed bars 57, carried indirectly by the shafts 50 and 50.

The corresponding .die for the shearing and cutting' punch justdescribed comprises as the respective the arrows the the I the ,the boxblanks,

terial forced thereinto by and die pair shown in Fig. 18 is adapted toform the first of the The said pairs are similar the paper 179 of thesaid punch cotiperates in alinesaidtbar terminating adjacent to an anecutting edge ment with the similar arc 186,.corresponding with thecurved portion 187 of the punch shearing edge 186. With dies and punchescome together in rolling contact in the direction-of circumferentialcutting of the box blank is efiected by means ofnla shearing cut whilethe conver ing sides of the tongue portion of the said lank are cutsimilarly by pressure of a cuttin edge against a relatively smoothsurface. he operation of the oppositely disposed pair of flap cuttingdies and punches 1s shown in a 19 wherein the same similar manner byFig. numerals are used as in Fig. 18 except that each is primed.

this construction In forming the transverse creases 190 in I 7 male andfemale creasing members are used such as for instance those shown indetail in Figs. 30 to 36, inclusive. Therein a male creasing member 192(or 192 or 192 or 192") is rigidly yet re 193 and movably held byadjustable means 193 in a suitable mounting 194 secured in turn in anysuitable manner upon the shafts 25 and 25. and one of the pairs being.immediately to the rear of the feed members shown in Figs. 20 and 21.Corresponding and co'ciperating with the said male creasing members arepositioned female creasing members 195 (or 195' provided withlongitudinally extendin slots 195 of various widths as shown in igs. 35and 36, the latter being a bar having slotsof four distinct widths 195which upon having-the box mathe working portiOns 196 of said malemembers, such as those" shown-in Figs. 34 and 35, forms the creases 190,upon which lines the blank may be folded to ultimately form a box.

The longitudinal creases in the blank are preferably rolled in by meansof rolls 197 secured by means of collars 198 to the shafts 16 hnd 16(Fig. 7) and adjacent to the feed rolls 15 hereinbefore described indetail. The radially outer surfaces 199 of said creasing rolls arecorrugated and coiiperate in such manner that the ridges of each forceinto the grooves of the other of each pair, this form of crease havingbeen found to bemuch better than those wherein a'single male memberrolls the paper into a female member.

When it is desired to set the ma-hne t a cut out blanks of a definiteepze. the lo -king members 200 are shifted upon their shaf': 201 toengage the teeth of gears 31'. 37" tfirmly hold them against rotationupon the shaft 25. Smce these gears are ;n intermeshing trains with thegears 38v 38", .38, 58'

' and 59, 59, as hereinbefore described, this entire system of gearsupon shafts 25, and 50,50 will be held against motion. The enumeratedgears and the creasing bars, punches and dies, which are connected tothem as hereinbefore described, are then freed upon their shafts byloosening up the set screws that normally secure them in position. Theintermeshing system of gears 27, 27, 28, 28, 52, 52' and 53, 53 fastenedto the shafts 25, 25 and 50, 50 outside of the side frames of themachine, as well as the other pairs of creasing bars, punches and diesthat are fast upon said shafts, are then rotated, by hand or by power,forwardly or backwardly, to circumferentially adjust the distancesbetween the several pairs of creasing bars, punches and dies. It will beunderstood that those members that are fast upon the shafts will movewith the shafts while the members that were loosened or disengaged fromthe shafts will be held against motion during this adjustment. When thedesired adjusted relationship is obtained, the inner system ofintermeshing gears together with the creasing bars, punches and diesconnected with them are again made fast upon their shafts and thelocking members 200 shifted out of engagement with controlling gears,when the machine will be in readiness for operation. The longitudinalpositionsof the punches and dies, as well as the shearing wheels and 46,may be adjusted upon their respective shafts by loosening the boltswhich fixed "position.

Having thus described my invention, what I claim and desire to protectby Letters Patent of the United States is hold them in normally 1. In amachine of the character de-,
